2 Sheets- Sheet 2 Patented Sept. 30, 1930 UNITED ST TES JOHN SIDNEY WILLIAMS, OF CLIFTON FORGE, VIRGINIA FEED-WATER HEATER Application filed 111175,

This invention relates to a feed water heater for use in connection with locomotives, the primary object of the invention being to provide means for utilizing the heat from the exhaust steam of the locomotive for heating thefeed Water.

An important object of the invention is to provide a device of this character which may be readily and easily installed without the necessity of making extensive alterations in the engine construction. v

Another object of the invention is to provide a water heater so located that it will be heated by the heat from the smoke box of the locomotive, in such a way as to maintain the outer wall of the device hot at all times.

lVith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction herein described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention. Referring to the drawings: Figure 1 is an elevational view illustrat ing the location of the device. 7

Figure 2 is a side elevational View of the device.

Figure 8 is a sectional view taken. on line 8 of Figure 2. V Figure 4 is a sectional view taken on line H of Figure 2. v

Referring to the drawings in detail, the de vice includes a body portion indicated generall b r the reference-character 5 the same being provided with a flange 6 at its lower end to be bolted to the steam exhaust pipe of a locomotive.

The body portion includes a wall 7 and an outer wall 8 spaced therefrom to define a passageway therebetween. The upper and lower ends of the passageway are closed by meansof the walls 9 and 10 respectively.

Extending downwardly from the upper wall 9 are partitions l l, the lower ends thereof being spaced from the bottom wall 10 of 192a" Saar i so. 290,600.

the body portion to allow free passage of the water through the passageway.

Partitions 12 extend "upwardly from the bottom 10 andhavo their upper ends spaced from the wall 9 to the end thatwater passing through the passageway must take an irregular course insuring thorough heating of the water. V

The reference character 13 designates a pipe communicating with the passageway, which pipe is designed. to direct water to the passageway where it will be heated by its contact with the heated inner wall 7 of the body portion.

At the upper end of one of the partitions 12, is a right angled wall 14 that connects with the adjacent partitioning member 11, as clearly shown by Figure 4 so that water entering the passageway will be compelled to pass throughout the entire length of the passageway in order to exhaust through the pipe 15, which has connection with the boiler feed pipe. 7

From the foregoing it will be obvious that due to the construction shown and described, the outer wall of the feed water heater will be heated by the heat from the smoke box, while the inner wall of the body portion will be heated by the exhaust steam passing therethrough. It follows that water entering the passage way will be thoroughly heated before it is fed into the boiler.

It will also be seen that the device may be readily and easily positioned or installed in a locomotive, without the necessity of making extensive alterations in the locomotive construction. l V

it might be further stated that a partitioning wall lfiextends through the center of the body portion and divides the steam to insure a heating of the entire inner wall, by distributing the steam to all portions of the interior of the body portion.

I claim: V

In a feed water heater, a hollow body portion, a partition extending throughout the length of the body portion for dividing the body portion into lateral passageways for the passage of steam through the body portion,

said body portion embodying outer and inner spaced walls defining a compartment, the upper and lower ends of the compartment being closed, partitioning Walls depending from the upper end of the body portion, the low r ends thereof being spaced from the bottom of the compartment, partitioning members extending upwardly from the bottom of the cornpartment the upper ends thereof being spaced from the upper end of the compartment to provioe a continuous passageway through the compartment, a feed pipe for directing Water to the passageway adjacent to the bottom of the compartment, and an outlet pipe oimnunicating With the compartment adjacent to the upper end thereof.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.

JOHN SIDNEY WILLIAMS.
